WINDOW.

SPECIFICATION forming part of Letters Patent No. 583,595, dated June 1, 1897.

Application iiled January 19, 1897. Serial No. 619,750. (No model.)

To @ZZ Lvl-wm, t may concern:

Be it known that I, HERMAN C. FUHLMANN, a citizen of the United States, residing at Eliza, in the county of Mercer and State of Illinois, have invented certain new and useful Improvements in Windows; and I do hereby declare the following to be a full7 clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in windows, and has more particular relation to window-sashes.

The invention consists of certain novel constructions, combinations, and arrangements of parts, all of which will be hereinafter more particularly set forth and claimed.

In the .accompanying drawings, forming a part of this specification, Figure l represents a perspective view of a sash embodying my invention, one of the locking-frames and the window-panes being removed. Fig. 2 represents a side elevation of the said sash, taken from the opposite side. Fig. 3 represents a vertical section throughv said sash on the line x Fig. 2. Fig. 4 represents an enlarged detail perspective view of one of the detachable frames.

A in the drawings represents the sash proper, B B the window-panes, and C C the movable frames. Said sash A may be made to receive either one or a plurality of panes of glass, and in the present instance is illustrated as being provided with four panes. The said sash is provided with a plurality of glass-supporting flanges a and vertical slots d', the latter being located at the tops and bottoms of the respective apertures for receiving the glasses. The upper and lower slots a are intersected by pin-passages d2, extending from the interior of the sash to said slots. Each of the frames C comprises side bars c c, a lower end bar c', connecting the same, and an upper bar c2, the reduced ends c3 of the latter being movably mounted in vertical slots c4, forming the upper ends of the side pieces c c. The lower end piece c is provided with an angular plate c5, secured thereto, so that one of its fianges projects in line with the said frame to enter its respective slot ce. The sliding pieces c2 are provided with similar angular attachments c6, the flangedv portions of the same being adapted to enter the upper and lower slots a as the said pieces c2 are slid forward in the side pieces c. Each of the flanges c6 is provided with an aperture c7. After the glasses have been applied in their respective recesses the frames G are laid over the same, the flanges c having been first introduced into their respective slots. The end pieces c2 are then moved forward to cause the flanges c6 to enter their respective slots and thus lock the frames firmly in position in the sash. The said end pieces c2 are held in this position by suitable pins o8, introduced into the passages d2 from the interior of the sash and adapted to enter the aperture c7 of the flanges c6.

It will be' observed from the foregoing description that as long as the pins cs remain in this position of engagement with the aperture c6 the end pieces c2 cannot be moved downward and the frame C removed, but should it at any time be desired to remove any one of the 'frames C to insert a new glass it is simply necessary to remove the pin o8 locking said frame in position and slide the end bars c2 rearward in the slots c4, which action will disengage the iiange c from its groove and permit the frame C to be removed from the sash.

It will be observed that by the employment of my invention the use of putty is altogether obviated, and the panes of glass are mounted in the sash in a firm and rigid manner by simply inserting the frames C into position and locking them by the pins o8. The said pins o8 are preferably provided with heads whereby they may be removed, said heads being countersunk in suitable recesses formed upon the interior of the sash. Should one of the panes mounted in my improved sash become broken, it is not necessary that the services of a skilled glazier be employed, as any child could remove the frame of the broken pane and insert a "new pane.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination with a sash provided with glass-supporting flanges and vertical IOO slots, of a frame comprising rigid side and top rails and a sliding bottom rail, and flanges mounted on the respective top and bottom rails and adapted to enter the respective slots in the sash tO lock the frame in position.

2. The combination with a sash provided with glass-supporting flanges and vertical slots, of a frame comprising rigid side and top rails and a sliding bottom rail, flanges mounted on the top and bottom rails and adapted to enter the slots of the sash, and means for holding the anges connected tO the sliding rail in the sash or releasing it therefrom at Will.

3. The combination with a sash having glass-supporting flanges, vertical slots, and a pin-passage in the said slots, of a frame adapted t0 be applied over the glass resting on said anges and having slots formed in its side bars, and a slide mounted in said slots and provided with an apertured iange adapted to enter the slot intersecting the pin-passage, a pin adapted to be passed through said pin-passage and enter the aperture of the said ange, and another ange mounted upon the lower portion Of the frame and adapted to enter the remaining slot of the sash, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing Witnesses.
